VENDING-MACHINE Specification of Letters Patent.

Patented May 11, 1909.

Application filed February s, 1909. serial No. 476,813.

ATo all whom it vmay concern:

Beit known that I, ALBERT E. DIETERICH, residing at Washington, in the District of (lolumbia, have invented certain new and useful Improvements lin Vending-Machines, of which the following is a specification.

My invention is an improved vending inachine and in its generic nature the invention embodies an improved coin mechanism, an improved strip guiding mechanism, ani-.nproved coin chute, an improved automatic chute closer and certain improvements in the coin insertible end of the casing.

In the art as practiced today there has coue into use a vending machine for selling postage stamps, soda'checks and the like in which the vendable article is contained in the for-n of a continuous strip, which strip is forned by folding a paper lengthwise upon itself and gunming the same at intervals toseparate the strip into pockets.` It is customary to omit the gum-ming in some in.

stances, such as when the strip-is to be used as a soda check. When the stripis used as a stamp selling strip, however,l the pockets are formed between the gummed parts of the The strip is also perforated at intervals to co-act with the feeding mechanism of the vending machine. In such vending machine the sales strip is fed step by step and the vended part is severed from, the remainder of the strip at predetermined intervals. Such machine `in its make-up embodies a rotatable operating shaft, a tri coin mechanism controllable from suc shaft, a strip feeding mechanism controllable pusher, (either directly or indirectly) and moves the pusher forward on its stroke tQ/ release the dog-.from its locking engagement with the shaft. This 'movementis practically instantaneous, andis imparted during 'only a small fraction vof the rotatable movethe limit of its stroke, the shaft'trip disengages the pusher and the pusher is instantly returned by a spring to its normal position, the locking dog, however, does notfall into its normal posltion in the locking notch of the shaft until near the end of-the rotatable cycle of the operating shaft, thereby leaving an open pass through the coin mechanism of the machine during approximately-more than three-fourths of the revolution of -the operating. shaft. This makes it necessary to insert but one coin at a time in -the machine and'carry Vthe operating shaft through its complete cycle of movement before inserting a second coinotherwise such second coin (and subsequent ones) will passjthrough'.

the open pass of the coin mechanism andlbe lost. To overcome this objectionable -feature is one of the principal objects of my present invention.

In the machine above referred to the continuous envelop is fed from the reel-to the feeding roll by what is known as the under feed, i. e., the strip leaves the roll at the down over the feedln drum." This xsomebottom and goes u an incline and then l times (when the contlnuous envelopis not gummed toseparate the pockets) causes the stamps or inserts to sli from one ocket to another, and vhence disarrange t e sales. A 4further object of my invention isto overcome this objection.V

My invention also has fofits object to pro-- vide an improved meansxfor'closing the coin chute when the machine is emptied or sold out so that a prospeetivepurchaser may -not insert his coin when the machine cannot deliver the goods.

Another object of my irnvention-is to improve the coin passage of the machine so that a straight coin ehutemay-be used.

In carrying ont the foregoing objects of my invention I provide a pusher havingcooperative connect-ion ywith the rotatable drive shaft whereby the-pusherwill be moved by the drive shaft to the limit of its stroke in one direction and not releasedto-come-back on its return stroke until the dog has entered its locking notch on a rotatable shaft `member. In other words the dog is returned to its locking position lbefore the pusher starts lneat thecoin slot after the pusher starts on it leaves the reel and passes toward the feedfp aperstrip butdro s when the strip has and arran ementof p arts all of which will .parts are in the position shown in Fig. 1.l

I also rovide means whereb t e pusher and ogV ma have adjusta le devices so that 'a coin o 4a predetermined size only will actuate the mech- In im rovin the stri ide I have provided mpeans hereby gngblver-feed in the sales strip to the feeding mechanism is maintained at all times and whereby the strip as consists o a pin ormember projectable'into' the. coin slotv to preventv passage -of a therethrough, the .projectable member 'b held out of the slot by arod that engages the passed from under tv e rod and through the medium of a bell 'crank lever, or its equivalent, moves the projecting member into the coin slot. y

My present invention also resides in those novel. details `of construction, combination be rstfu ly described, then be specifically pointedjout lin the appended claims, and

illustrated in the` ,accompanying drawings,

Fig. 21, is a detail .view bf a modification when two coins are ecessary to operate the coin mechanism. @Referring now to the accompanying drawwhich like letters and numerals of reference indicate like arts in all of the figures, I will first indicate those parts of the machine which are old in the art and which,l per se, constitute no. art of my invention. Such old A.parts consist of the supporting frame 1 fwhich has a cut-away port1on or opening 22. The-.frame 1 has a bearing to support the ro- -t'atable operating shaft 3, whose movement is-limited to one direction by the ratchet and -pawl mechanism disclosed in Figs. 1 a, 28L and 3*-, respectively. 6 designates a cam member mounted on the shaft 3 to turn therewith, and the cam member 6 has a notch.63 for the locking dog to enter'. 2 represents the feeding geared with the shaft 3 by mutilated gear connections 4-5.

The support 1 has a web 14 to yprevent coins` from interferingwith the mechanism above the web, and is alsov provided with 'a bearing 11 for the cutter shaft 10` on which the cutter bell crank lever 7 is mounted, the bell crank lever 7 havin a portion 8 provided with an anti-friction vro er 9 that is adapted to enter the cam `groove 9 in the cam'member 6. The bell crank lever 8 carries the cutter 12 that coperateswith the fixed cutter .13. The back check mechanism for the shaft 3 consists of a disk 73 havingban internal ratchet face 7 4 to be engaged v7 6, pivoted at 77, to aiiXed stud that maybe .secured to the web or support 1 in any approved manner. LIn adapting the back check mechanism to my improved coin mechanism I find' it advisable to insert an additional ratchet tooth 75, as shown in the drawings.

0n the drum shaft 2 on the front side of the web 1 is a feed drum 15 which is guarded Fig. 7, is a detail elevation of thev removable by an encircling guard 16 and a stripping y a pawlshaft which is I.

,machine hereinbefore describe( guard 19 between which the continuous envelop 89 passes, the guard 16 being secured at 17 and 18, as indicated.

A bearing 2() is provided for the slot closure rod 120.

i 21 designates the delivery slide onto which the severed sections of the envelop are delivered and from which they are ejected from the machine.

j Thoseparts desi ated by the numerals 1 to 22 inclusive and y the numerals7 3, 74, 76 and 77 inclusive, per se, form no part of my present invention, as they are arts of the as being known in the art. My invention consists in the rovision of the parts other than those num ered as just above referred to. By reference to Figs. 1 to 3 of the drawings my improved coin mechanism will be readily understood.

In carrying out my invention I close the aperture 22 by an insert plate 23, shown in detail in Fig. 9, the plate 23 having lugs 24, 25, 26 and 31 which overlap the web or su port 1 and which may be rivetedthereto to form an integral part thereof. The plate 23 is also provided with a table 28, whose forward end is downwardly bent as at 29, a lug 30 being also provided for a purpose presently to appear, and the lug 26 is also provided with a projecting wall 27 for a purpose which will also be hereinfter made apparent.

My improved pusher 37 is shown in detail in Figs. 5, 6 and 7, and comprises thearrn 35 cut away as at 44 to receive the head of the pivot screw 36 that screws into a bearing lug 99, cast integral with the web or support 1,

-the web 14 being notched out to receive the pusher rod 37.

39 designates the coin slot or passage of the pusher 37 and 42 and 44 designate slots, one for the securing screw 47 and the other for the screw 36, so as to retain the pusher in position and at the same time permitreciprocating movement to be imparted thereto.

38 designates the gate or cut-olf of the pusher and 41 represents a heel that is adapted to engage a bumper 59 to render the operation of the machine as noiseless as possible. j

A set screw 60 cooperatesA with the coin slot39 of the pusher and through the medium of the set screw 60 the pusher may be adjusted to take a coin of only a predetermined size.

The dog 61 which cooperates with the depression 63 of the cain 6 to lock the shaft 3 normally from rotation is another part of Inv improved coin mechanism, the dog 61 being pivoted by a screw 62 that enters the lug 31 of the plate 23, which lug forms a bearing for the screw 62. The dog 61 has -a downwardly projecting portion merging with a rearwardly projecting portion 64 that is slitted at 65 to receive the coin in its passage through the machine, an adjusting screw 66 being provided to co crate with the screw 60 to adjust the mec anism for a particular coin.

The coin chute 68 is undercut to forni a shoulder 69 beneath which the projection 64 of the dog 61 is located for a purpose presently to appear.

The dog 61 is normally held in engage- Ynient rwith the cam 6 by gravity or by a spring 67.

The pusher rod 37 at its forward end has its arm 35 providedwith a hardened steel piece 48 that is secured to the arm 36 in a socket to be flush with the front face of the arm 35 andthe steel piece is provided with a notch 49 to form a tooth 51 whose other side is formed by a deplression 50 of greater depth than thenotc 49 to coperate with the tooth 54 on a disk 52 secured at 53 to the. face of the cam 6. The disk 52 has a shoulder or toothed portion 55 to copei'ate with Ythat 50 of the toothed steel piece 48, theY 'disk 52, the curved surface 56 extending through an arc of ap roximately 270 and merging with a muti ated portion 57 that pro'ects at the tooth 54.

he pusher 37 and the iece 48 has a curved or beveled under-sur ace 71 to cop- .erate with an adjustable support at times, the support 70 having a curved or beveled face 72 tov contact the surface 71 of the pusher when the pusher is at the limit of its working stroke.l The pusher is adapted to be returned and retained in its normal position withv the coin slot 39 under the chute 68, by a coil sprin 58.

The strip is ed from the reel to the strip `feeding mechanism. I provide a spindle 32 on the .plate 23 on which the roller 84 that carried the reel 86 is mounted, the spindle and reel being held in place by a wire clip 33 that is pivoted at 34 onto the plate 23 in the usual manner. A table 81 is provided that lies in a horizontal plane at the uppermost level of the feeding mechanism which consists of the dium 15 and the bearing for the Shaft 3 over which the strip passes. The ta ble 81 is secured -by a plate 83 to the web or support 1, and has its forward end 82 curved to prevent'tearing the strip. A guard 78 cooperates with the table 81 to hold the strip l down on the table and also to guide the strip from the top of the full roll 86, see dot and dash lines in Fig. 16, over the table 81, the guard 78 having ears 79 through which the guard maybe secured to the web or support 1 block 105 and connects with the rod 120, see.

sage from the reel into the feeding mechanism as nearly horizontal as practicable at all times.

l also provide a guard 87 to engage the ro-I jected end 89 of the sales strip, a's it is fe( between the cutters 12 and 13, the guard 87 being bent up at the front end orl down at the front end as 'conditions may require. bendingthe guard up at'the front end any tendency of the paper to feed laterally toward the support 1 is obviated, or should the projecting end havo a tendency to feed the )aper away from the table or support by bending the forward edge of the guard 87 down this will be compensated for, the guard 87 being secured at 88, as indicated.-

'In the modified form of coin mechanism disclosed in Fig. 14, the construction of the pusher 37 is thc same as in the other figures except that the screw 36 may be omitted. In this form of my invention I provide the pusher with a stud 96 to be engaged by the fork 95 of the bell crank lever 94, pivoted through its bearing 91 on a screw 92 that enters a fixed part of the supporting frame, and the bell crank lever has lts other leg 93 rojected across the face ofthe cam disf, which cam disk has a in 90 to engage the leg 93 of the bell crank lever, the parts being in their normal position, as shown in Fig. 14. When the shaft 3 is turned in the direction of the arrow in Fig. 14, during the first movement that takes place the pin 90 moves to the position 97 to rock the bellcrank lever to the position shown in heavy dotted lines in Fig. 14, to move the pusher forward a corres ending distance to move the coin 100 to t 1e position shown in 101 in heavy dotted lines, thus elevating the dog 61 out of the notch on the disk 6 and permitting further movement o n the shaft 3,. As the shaft 3 is, turned with the pin 90 from the osition 97 in Fig. 14, to the position 98 in ig. 14, the balance of the movement ofthe pusher 37 willvhe effected and the coin moved tothe position .102 where it is dropped or ejected. About the same time the dog 61 again enters the notch in the cam or disk 6 and as the shaft 3 is turned to complete its revolution.

which it will be seen that a block 105 secures the coin chute 68 to the support 1. The block 105 has a bearing 106 for a pin 107 that engages the fork 1,09 of a bell crank lever 108 which is pivoted at 111 to the' Figs. 17 and 18, it being understood that the rod 129 is bent at the necessary places to cause it to conform to the configuration of the casin in which the works are inserted. So long ast e sales strip is under the rod 120 (see Fig. 16) the bell crank lever 108, will be maintained in the position shown in Fig. 17, to prevent the'rod prpin 107 from being inserted in the coin slot 68, but when the end of the sales strip or envelop passes from beneath the rod 120, see Fig. 16, such rod will drop, thereby causing the bell crank lever 108 to rock on its pivot and projectl the pin 107 into the coin slot 68, audthus preventa |coin being inserted.

he works of this machine lare adapted to `be yinserted in asuitable case, the upper or coin passage portion of which. is shown in Figs. 19 and 20, by reference to which it will be seen that the case. 112 carries a coin piece holder 114, milled at 115, to the size of the desired coin, the milled portion 115 merging with the back end of a cut-away part 113 in the top of the case 112, and being heid in alinement with the coin chute 68. The front of the case 116 is provided with a lip 117 to cover so much of the cut-away part 11.3 asis in advance of the coin holder 114, see Fig.` 19. This makes iteasy to provide the insert opening through the top of the case 112 without`the necessity of boring or cutting a slot the size of a coin therein.

Operation: I will first describe the operation of the coin mechanism. This will be best understood by reference to Figs. 1 to 3 inclusive of the drawings, which show the three cardinal positions of the mechanism. Normally the parts are positioned as shown in Fig. 1. A coin is dropped into the chute 68 and gravitates to the Aposition shown in Fig. 1, the `operator turning the shaft 3 (through a handle or anyv other equivalent means) causes the shaft 3 to be turned in the direction of the arrow in Fig. 1. The first thing that takes place, is that the tooth 54 engages the tooth 51 and locks the pusher to the disk 52, the .movement of the shaft 3 from the position shown in Fig. 1 to that shown in Fig. 2, causing the pusher to .be reciprocated in the direction of the arrow in Fig. 2, fromthe position shown in Fig. 1 to that shown in Fig. 2, to bring the' coin 100 under the projecting part 64 of the dog 61 and raise the end out lof the notch 63 in the cam 6, thereby unlocking the shaft, it being understood that. the/movement of the shaft 3 from the position shown in Fig. 1, to that shown in Fig. 2, isalways accessible as free movement.

Itis to be noticed that the coin while the parts are positioned as shown in Fig. 2, is

from the position shown in Fig. 2 to the 'position shown in Fig. 3, which is the limit of its movement. At this time the lcurved surface 56 of the disk 52 enters the curved part 46 of the pusher and locks the pusher from reciprocatlon in either direction. The pusher remains locked until the shaft 3 has about completed its cycle of movement and the mutilated Iportion 57 coni-es over the pusher when thepusher will be released and )rought back to the position shown in Fig. 1, by the spring 58, it being understood that from the time the pusher leaves the position shownin Fig. 1, until it again arrives at such position the cut-ofi' or slide 38 will be under the coin chute 68 and prevent a second coin dropping into place. 'lhe web 27 of the lug 26 acts in connection with the web 14 as a guard.

Should it be attempted to operate the coin mechanism with a coin smaller than that .of the predetermined size but large enough not to run through the pass of the coin mechanism by holding the coin in any manner between the pusher and the projection 64 lof the dog so as to elevate the dog out of its vlocking notch, suchv action will cause the )rejection 64 to engage the shoulder 69V and lock the pusher from further movement, thus preventing a smaller coin operating the machine.

During the first turn of. the shaft 3, throughthe iirst part -of its cycle of movement, the shaft 2 will be rotated to feed al section of the continuous strip through the cutting mechanism, after Which the shaft 2 will cease its turning and a further movement of the vshaft 3 will actuate the cutting mechanism to sever the projecting part of the strip in the usual manner.

The modified form of coin mechanism disclosed in Fig. 14, operates similar to that shown in Figs. 1 to 3, inclusive with this eX- ception that the return of thepusher 37 from the limit of its movement in one direction to its initial position is instantaneous after the mutilated part of the disk 52 alines with the pusher, Whereas in the form shown in Fig. 1,4 the return of the pusher is gradual. 'lhis is accomplished in the followingmanner: The first movement of the shaft 3 in the direction of the arrow in Fig. 14, from the position JO to the position 97 unlocks the dog 61,- a further movement from the position 97 to the position 98 ejects the coin `coins* may be inserted in the chute ibeone rthe shaft 3 -is turned and that a continuous tuming of the shaft 3 so long as any coin is in the chute will perform successive operations in the mechanism. For instance, if seven coins are placed in the. chute and-the opwator then begins to turn the shaft 3 he can keep on turning until seven strip sections are delivered to him, but no longer.

From the foregoing description taken in connection' witht'e accompanying drawings it is thought the complete constnuction, operation and many advantages of my invention will be readily understood by those appertains.
